FAQ
Is it easy to install?
Yes. The DOREXS FILTERS is designed for standard electrical panel integration with clear wiring diagrams and multiple mounting options. The installation process requires only basic hand tools and follows the same inline connection method used by all major power line filters.
How long does it last?
Built with industrial-grade components - including capacitors rated for high AC voltage and inductors with saturation-resistant cores - the DOREXS FILTER is engineered for 100,000+ hours of continuous operation. EMC compliance enhances the longevity of electrical systems, and this filter is designed to maintain performance throughout its service life. EMC regulations help reduce equipment damage risks.
Does it meet medical device standards?
Yes. The low leakage current design supports compliance with IEC 60601-1 medical safety requirements. EMI filters can protect medical devices from electromagnetic interference, and low-leakage configurations are available for Type B, BF, and CF applied parts. Power line protection improves overall system performance in sensitive medical environments. Single-phase filters provide high performance and low leakage current.
What if it doesn't fit my application?
DOREXS offers custom filter designs tailored to specific requirements, along with a 30-day return policy for standard products. Whether you need a different current rating, specific terminal type, or optimized attenuation for a particular frequency band, our engineering team can help.
Can you provide test reports?
Complete EMC test reports, insertion loss curves, and safety certifications are available upon request. Manufacturers increasingly require full traceability documentation, and DOREXS provides detailed performance data so you can verify that EMI filters meet compatibility standards for reliable operation of electronic systems.
What's the difference between single-stage and two-stage filtering?
Power line filters are available in single stage and multi-stage designs. A single stage filter uses one LC section and provides good performance for less severe interference environments. The DOREXS FILTER's two-stage design adds a second LC section for significantly stronger attenuation - particularly in the 150 kHz to 1 MHz band - delivering the excellent performance needed for demanding industrial and medical applications. EMI filters suppress high-frequency electrical noise on power lines, and the multi stage approach does this more thoroughly.
